The National Weather Service (NWS) has issued a Dense Fog Advisory for Spokane, effective until midday Tuesday. Residents and travelers are urged to exercise caution as the dense fog significantly reduces visibility on roads, highways, and city streets, possibly to near-zero levels in some areas, creating hazardous driving conditions. This advisory impacts not only Spokane’s downtown area but also surrounding towns and major routes, including Interstate 90.
The dense fog is primarily caused by a weather phenomenon known as temperature inversion, where cooler air near the ground is trapped beneath warmer air above. This situation has been amplified by recent overcast conditions and light rain, leading to particularly thick fog. Common during winter, this fog can linger into midday due to calm winds which slow its dissipation.
Motorists face substantial risks, as visibility may fall below a quarter mile, especially during the early morning hours. The NWS emphasizes the importance of safety measures: drivers should use low-beam headlights, increase their following distance, and reduce their speed to navigate these challenging conditions safely. Local authorities recommend avoiding unnecessary travel, particularly in the mornings when fog density is at its peak, and encourage travelers to stay informed about current road conditions through local traffic updates.
Pedestrians are also advised to wear bright or reflective clothing to enhance visibility during foggy periods. With winter presenting frequent fog advisories in Spokane, residents are reminded to remain vigilant about potential low visibility, particularly after any precipitation.
While the fog advisory is set to lift by Tuesday midday, the NWS warns of potential continued fog formation through Wednesday, with conditions slowly improving as the week progresses. Community preparedness and awareness are crucial during these weather events, underscoring the vital role of the NWS in informing the public about such hazards.
Navigating through Spokane’s foggy conditions requires adherence to safety guidelines and regular updates from weather authorities. As visibility improves, the advisory will be lifted, yet residents are encouraged to proceed with care in the coming days. The NWS continues to play an essential role in enhancing public safety through effective communication and alert systems during adverse weather conditions.
